potassium reacts the most vigorously.
Answer:
25002m
Explanation:
V = 100 km/h
Converting to m/s, we have
V = (100 x 1000)/3600 = 27.78m/s
t = 15mins = 15 x 60 = 900secs
Displacement =?
Velocity = Displacement /Time
Displacement = Velocity x time
Displacement = 27.78 x 900
Displacement = 25002m
Since displacement and distance are measured in same unit, the distance between A and B is 25002m
Calculate the number of valence of ammonium ion (NH4+) and chloride ion (Cl-)
for ammonium ion = 4 +5-1(lost electron) =8 valence electrons
for chloride ion 7 +1 (gained electron)=8 valence electrons
The lewis structure is as in the attachment below
